Tooll whom it may concern:

Be it known that I, HABRY Gr. Belorussian, a citizen of the United States, residing at the city of St. Louis, in the State or" lissourL; have invented certain new and useful Improvements in Combination- Locks for Motor-Vehicles, of which the following is a specification.

This invention relates to automobile locks of the type in which a movable valve is interposed between the carburetor and the intake manifold. While the drawings show describes the said valve in this'devioe as so located, substantially it not identically the same result can be attained b y-locating the -said valve at a suitable point in the exhaust manifold, the conthe device and its mode of 0pis relative to the exhaust manifold or the intake manifold. I

In the accompanying drawings forming a part of this specification. in which like wherever they occur,

numbers of reference denote like parts Figure 1 is a diagrammatic side elevation showin the instrument board of a motor vehicle, t e engine, the intake manifold, the carburetor, and means in proper relation thereto;

Fig. 15 is a section taken on the line 15-15 in Fig. 1.4. looking in the direction oi the arrow.

The chassis 1 supports the radiator 2, instrumcnt board 3. and engine 4: in the usual manner.

The intake manifold 5 extends from the cylinders as is common and the carburetor 6 is bolted thereto by the usual bolts '4' which pass through holes in the flanges 8 and 9 in the millimeter and intake manifold respectively and through theslotted holes 18, ll, and 12 respectively in the body plate 13, in termediate plate 14-, and body plate 15., Fig. 8 shows in dotted lines the approximate shape andarrangement of body plate 15 (to which plates 13 and H correspond} in case this lock is to be fitted to the ii-type engine of an eight or tiveive cylinder engine.

ll'hen nuts 16 are tightened on bolts 7 passing through the holes 10, 11, and 12, this loci: is tightly fastened between the car: bureter t5 and the intake manifold 5. and reniovel of this loci: from between the same ill leave the carburetor and intake inanifold dismounted. disconnected, and in inoperative condition.

i urning the knoh 17 in either direction revolves the flexible shaft contained within the housing 18. which shaft will he prefer ent shape from the tail 30 and thus indicating the degree of movement or rotation of the dial 2? relative to the index point 31. The said degree of rotation may be determined also by the ball 32 riding into and 5 out of the notches 33, the said ball being spring pressed by spring 34. On account oi the flexibility of the shaft within housing 18 and of the said housing connection is easily made between the rotatable knob 17 and the arbor 22, no matter where the carbureter 6 may be located relative to the instrument board 3.

Pin 21 is adapted to slide in slot 35 in head 20 in tight Connection with the flexible shaftby means or the rod While pin 21 can slide in slot 35 in a longitudinal direction the turning of head forces turning of the arbor 22 because ot' the diameter of pin 21 being substantially the same as the 20 width of slot 35. The head 20 of the flexible shaft is in tight engagement with the plate 36 cast integral with body plate 15 of which 7 hmisingil? and boss 38 form a part. The

head. 20 is larger in diameter than the open- 25 ing through the end 39 of housing 18 and its movement is therefore limited in that direction. The end 39 is gripped and clamped by bolt 40 in jaw 41. This mode of attachment of the flexible shaft to the arbor 22 prevents pulling apart of the permutation tumblers 23, 24, and 25, due to the road stress on the engine or frame of the vehicle and insures prompt and accurate working of the lock because the pin 21 and arbor 22 will.

be'turned bv the bifurcated head 20 ottheflexible shatt no matter in what part of the slot 35 the pin 21 happens to be. l

The arbor is fixed to plate 13 and passes loosely through plate 14 and loosely 40 into a drill 43 in arbor 22.

' Tumblers 24; and 25 are so mounted on arbor 4:2 as to be adapted to rotate around it. Cam tumbler 23 is fixed to arbor 22 but by means of drill -13 is loosely mounted on arher 42 so as to be adapted to rotate therearound. Pin 44 on tumbler is adapted to engage with pin 45 on tumbler Pin 51-6 on tumbler 24: is adapted to engage with pin 47 on tumbler 25. The working oi the 50 tumblers 23, 2 1, and 25 by means of knob '17 through the instrumentality of the flexible shaft that terminates in the head 20 brings the slots as into alinement opposite arm 49, which is the position shown in Figs.

35 11 and 12. This is the open position, which in rotation in'either direction (the direction depending upon the combination) of the knob 17 will cause valve 50 to be moved upward in Figs. 11 and'12 so as to remove it 60 from closing hole 5.1. in plate 15 and hole 52 (so Fi ll. to'the dotted line 051M011 in the nesacee same figure, gas can pass freely from the carburetor 6 into the intake manifold 5, permitting the operation of the engine, which is impossible when holes 51 and 52 in plates 15 and 130i this look are closed by valve 50.

Valve 50 slides in an elongated slot 53 in plate 14, one end of the said slot substantially coinciding with the holes 51 and. 52 in plates 15 and 13 and the other end of the said, slot terminating in the centering cutout 5 1 in which the big 55 seats whenever the valve 50 is fully open. The rounded shape of the corners 56 of the said slot 53 additionally tends to center the said valve 50, which centering as well as the scallops 57 in the side of valve 50, tend to'prevent bind ing of the same against the walls of slot 53 during the travel of the valve 50.

Pivoted'gat 58 in. the slot 59 is an arm 60 which atits opposite end is pivoted on a1- bor 42.

Pivoted on stud 61 which is fixed to arm 60 is a trigger 62, to which trigger 62 arm -19 is fixed or of which said arm 49 may form an integral part. A spring 63 is ineugaga ment with the said arm 49 and also with a point of fixation 64 on arm 60-, which spring so acts as to tend always to force arm 49 into slots i8 when the three slots 48 are opposite it, i. a, in registration with each other. 1

When one or more of the said slots 48is not in registration, the periphery of its tumbler holds arm 49 back under pressure of spring 63, which is made possible by the indentation in'camslot 66 in which slot pin (37 travels whenever valve 50 slides in slot 5-3. The said pin 67 enters indentation only when the valve 50 is in closed position, c'. 0., covering the holes 51 and 52, and furthermore only when pressure of the periphery of one of the tumblers forces the said pin 67 into the said indentation (35. Pin 67 is released through indentation 65 bysuch manipulation of the tumblers 23, 24, and 25 as works the combination and causes 31111811101113 of the three slots 48. Thereupon the lock stands unlocked and rotation of arbor22 by knob 17 causes the valve 50 to slide to the open posi' tion. Slot 66 and indentation are cut through plate 14: and underlying the same is channel 68. A countersink 69 is preferably cutin the interior side of plate 13 so as to prevent cramping of valve 50 in its movement.

The holes 10, 11, and 12 are elongated to accommodate'any variation in sizeof carburetors and intalie manifolds, the valve 50 being made of a size large enough to cover fully the outlet from the carbureter and the intake ot' the intake manifold in such machines as have those openings of the largest diameter.

Washers 70 are interposed between tum .blers 23, 24., and and between washer 25 and arm. (30. Spring '4' 1 impinges against where to any car.

' aeaoao The dial H may be used for various useful purposes, included among which may be mentioned its use as a phony until the true combination is determined by readjustment of the tumblers with relation to knob 17 and its associated parts.

It will be understood that if desired tum-- blers 2- and 25 may be provided with a plurality of holes to permit of'change of 'location of the tumbler pins, such plurality of holes not being shown in the drawings but only one hole indicated for each pin shown.

Countersink in plate 15 is opposite countersink 69 in plate 13.

'hen the device has been assembled'as hereinbefore described, and screws 73 have been inserted in place, the edges of plates 13, 14, and 15 are soldered together, making a unitary whole of the casing composed of the said plates and preventing any air or gas leaks past the edges of the said plates or between the said plates.

The tumblers are first set according to dial 74, then the flexible shaft is led to a point adjacent to instrument-board 3, then shaft 76 is passed through the said board and its end into the split collar 77 having therein a plurality of slots 78 and external screw-threads 79. The dial 27 is then set to the same number as the dial 74, while the flexible shaft is held tight and the nut 80 screwed home oh threads 79.
